What problem does it solve?
This Skill helps you avoid fragile or misleading smart contract tests by focusing on edge cases, fuzzing, fork realism, and stateful invariants that catch costly bugs before deployment.
Core Features & Use Cases
- Unit testing with meaningful assertions: Verify failure modes, access control boundaries, economic properties, and event emissions rather than trivial getters.
- Fuzz testing for input-driven bugs: Use Foundry fuzzing to exercise math and user-input handling across many randomized cases.
- Fork testing for integration correctness: Validate interactions with real external protocols on a mainnet fork to detect integration issues that mocks hide.
- Invariant testing for stateful systems: Ensure critical properties always hold across long sequences of randomized calls.
Quick Start
Use the testing skill to design Foundry tests for your contract that cover edge cases, fuzz inputs, fork external integrations, and add invariants for stateful behavior.
